How to separate parts from a glue bomb
Posted by 1TOYTRUK on Tuesday, August 4, 2020 6:11 PM

I have a German Revell '31 model A sedan delivery, made in '74/75 that a friend sent me, he got it from a garage sale 40yrs ago.

So whom ever started building didn't get very far as they only glued up the chassis to the fenders assembly, never to come apart by the amount of clear glue used!

Ive never had to try to take anything like this apart  before! 
l looked at UTube but not liking anything I found!
I hope someone here has had success in removing glued up parts?

I have heard of wetting the item, putting it into a plastic bag and placing it into the freezer for a while to help break the glue joints might work.

What I have done;

 That glue Bomb doesn't like freezing cold. The thing is. When you freeze it don't let it get warm while working to dissassemble it. Keep it cold then re-freeze it, if things don't pop right away. patience is a virtue here and do not WET it!

 One other thing I can recommend is this. There is a company that makes Stainless Steel P.E hobby saws of many shapes. They are also different thicknesses. If you can find those try using them in conjunction with the Sharp # 11 blade!

    Some of those saws are no bigger than one of those large paisleys you used to see all the times on hippy shirts!

The problem might be that often times, these molded in color plastics can become very brittle over time.

freezing could possibly make it more so.


I recently had a conversation with a gentleman on another forum about the problems associated with the use of plastic cements.

This is a prime example of why I don't like them.

Yeah - glue boms can be challanging, but don't freeze it. Been there done that.

Old plastic gets brittle over time, and can shatter into more pieces than you'ed care to work with.

I just got a glue bomb for the engine, Chrysler cross-ram long tube, and knew it was going to be a beast to separate from the chassis, and it was, and the engine dis-assembly was about the same, but at least I have the (Broken) bones to restore it and it was complete, and I have a bag of spare parts.

I'd say just take your lumps as you carefully dis-assemble it, and be prepared to do some repair work.

Old stuff is cool and can be fun (Challanging fun) to bring back from the dead and give it new life Thumbs Up.

Thanks Guys, I thought about freezing it, & being so OLD, it probably will be somewhat brittle,as the plastic has lost platizer, & how it was stored over time? The other thought is to just remove, clean up the access glue as best I can & carefully paint the chassis after the fender assembly is painted.

Not the way I like to do things!

All the chromed parts are delaminating from the plastic, Molitow should fix that or the other methods to redo the chrome!

The models engine was the old 4 banger, tho in the box was a early complete Hemi which I guess was going to be used, & l will use!

If per chance it was glued using Testers tube glue, then brush on the glue seam with mineral spirts, it will soften the glue. Keep brushing it on and work the parts apart. Worked for me with good results, good luck.

That's a Thought! Long time since I used Testors glue, but isn't it have a Yellow, Orange hue to it?

After more thought on glue type I think might be a clear glue made by Araldite? which is a English glue, from memory it was used quite a lot back then & my mate is in Australia & that's where the kit came from.

im not going to rush into it, still considering the options youall have suggested! Thanks

Hey, all!

First time I've ever heard of the freezing technique, have to give it a try someday as I love to dismantle and restore previously enjoyed, but unloved, glue bombs. 
All the ones I've done so far, look like they were slopped together by a preschooler and that's good news! The tons of glue hasnt had time to melt the surfaces so they can be carefully pried apart with no damage to the plastic. A fresh #11 blade can cut the glue easily as well, if you've got the room.

Just passin' through......

 Seems to me the only glue I remember like that is Ambroid. It had or has a Yellowy/Orange hue to it.It was a general purpose glue. Not good on the various plastics, but great for wood.
